Granted: 1995-05-23
Abstract: There are disclosed normally tacky, pressure-sensitive adhesive compositions comprising one or more normally tacky polymers having a Tg of about 0° C. or less and containing pendant functional groups attached to the backbone and having the formula:                            in which R1 is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano, the polymers preferably also being normally tacky when cured.

Pressure-sensitive adhesive, water-based emulsions containing such polymers and pressure-sensitive adhesive articles comprising a substrate having at least a portion of one surface thereof coated with the adhesive compositions are also disclosed.  In a preferred embodiment, the adhesive compositions further include a polyacid component for further improving cohesive strength, particularly at acidic pH.

Title: Wireless communications systems
Inventor: MESSENGER STEVEN
IPC: H04B1/69
Filed: 1989-08-24
Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE A wireless packet communication system is operable in a frequency band occupied by other transmission sources. The system includes a base station and several remote stations. Each remote station has a transceiver for transmitting and receiving data packets on electromagnetic carriers. The carrier frequency of the transceiver is selected in a pseudorandom manner from a predetermined set of carrier frequencies prior to transmission of each packet or in response to detection of transmission errors. Each carrier frequency may be associated with a unique pseudorandom noise code used to spread spectrum encode packets. The base station has a number of transceivers which operate simultaneously at the different carrier frequencies and which generate differentnoise codes for spread spectrum encoding and decoding. The base station records data for each remote station identifying the transceiver which last received a data packet and transmits packets addressed to each remote station with the identified transceiver.
